Why is it Necessary to Bake PCBs before SMT Processing?

In the field of SMT (Surface Mount Technology) processing, details determine success. From the preparation of raw materials to the final product inspection, every step is crucial. Among them, the baking process of PCBs before processing is an indispensable step. Let's explore with Charmhigh Electromechanical why it is essential to bake PCBs before SMT processing. Interested friends, let's dive in.

PCBs, as the core components of electronic products, directly relate to the performance and stability of the entire product. Long-stored PCBs, if not properly treated, may accumulate a significant amount of moisture inside. This moisture can rapidly expand during the SMT processing, especially in high-temperature environments, causing irreversible damage to the PCBs. Therefore, baking PCBs before processing becomes an important pretreatment step.

The primary purpose of baking is to remove moisture from the PCBs. By heating, the moisture inside the PCBs evaporates, reducing its potential threat. This step is crucial for improving product quality and reliability.

However, it's essential to pay attention to some details during the baking process. For example, excessively high temperatures or prolonged baking time can cause PCB deformation, affecting subsequent processing. Therefore, when setting baking parameters, it's necessary to precisely control them based on the PCB material and thickness.

Additionally, after baking, PCBs must undergo rigorous inspections to ensure they meet processing requirements. If any issues are found, timely handling is required to avoid adverse effects on subsequent processing.

In conclusion, baking PCBs is a crucial step in SMT processing. It not only improves product quality and reliability but also ensures the smooth progress of the processing. Therefore, every enterprise engaged in SMT processing should attach great importance to this step.
